| 2 | Geological constraints of giant and medium-sized gas fields in Kuqa Depression显示文摘There is a gas-rich and well-charged petroleumsystem in the Kuqa Depression where Triassic and Jurassicsource rocks play important roles. Distributed in an area ofmore than 10000 km and with a thickness of up to 1000 m,they are composed of dark mudstones, carbonaceous mud-stones and coal seams containing 6%, 40% and 90% of TOC,respectively, and are mainly the humic organic matter. Ashigh-quality regional cap rocks, the Neogene and Eogenegypsum rocks and gypseous mudstones matched well withthe underlying Neogene and Cretaceous-Eogene sandstones.They have formed the most favorable reservoir-seal assem-blages in the Kuqa Depression. Also the Jurassic sandstonesand mudstones formed another favorable reservoir-seal as-semblage. The traps are shaped late in the fold-thrust belt,mainly fixed in the Tertiary-Quaternary, where ten structurestyles have been distinguished. These traps spread as a zonein N-S, are scattered like a segmental line in W-E and showtier-styled vertically. The best traps are gypsum-salt coveredfault-bend anticlines related to the passive roof duplex. Thispetroleum system is characterized by late accumulation. Inthe early Himalayan Movement, mainly gas condensate andoil accumulated and were distributed in the outer circularregion of the kitchen; whereas in the middle and late Hima-layan the gas accumulations mainly formed and were dis-tributed in the inner circular region near the kitchen. Theoverpressure of gas pools is common and is formed by sealcapacity of thick gypsum layers, extensive tectonic compres-sion and large uplift. The well-preserved anticline traps un-derlying the high-quality regional cap rocks of the Tertiarygypsum rocks and gypseous mudstones are the main targetsfor the discovery of giant and medium-sized gas fields. Aboveconclusions are important for the petroleum geology theoryand the exploration of the fold-thrust belt in foreland basinsin central and western China. | JIA Chengzao GU Jiayu ZHANG Guangya | 2002 | Chinese Science Bulletin2002，47，S1： | 17 |
| 3 | Multi-agents modelling of EV purchase willingness based on questionnaires显示文摘Traditional experimental economics methods often consume enormous resources of qualified human participants,and the inconsistence of a participant’s decisions among repeated trials prevents investigation from sensitivity analyses.The problem can be solved if computer agents are capable of generating similar behaviors as the given participants in experiments.An experimental economics based analysis method is presented to extract deep information from questionnaire data and emulate any number of participants.Taking the customers’willingness to purchase electric vehicles(EVs)as an example,multi-layer correlation information is extracted from a limited number of questionnaires.Multiagents mimicking the inquired potential customers are modelled through matching the probabilistic distributions of their willingness embedded in the questionnaires.The authenticity of both the model and the algorithmis validated by comparing the agent-based Monte Carlo simulation results with the questionnaire-based deduction results.With the aid of agent models,the effects of minority agents with specific preferences on the results are also discussed. | Yusheng XUE Juai WU Dongliang XIE Kang LI Yu ZHANG Fushuan WEN Bin CAI Qiuwei WU Guangya YANG | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，2： | 14 |
| 4 | Geologic Characteristics of Volcanic Hydrocarbon Reservoirs and Exploration Directions in China显示文摘Volcanic rocks are distributed widely in China, which are important exploration targets. By analyzing many discovered volcanic hydrocarbon reservoirs all over the world, the authors summarized the geologic characteristics of the formation of volcanic hydrocarbon reservoirs in China, and gave further exploration directions and advices. (1) There are mainly Carboniferous-Permian, Jurassic-Cretaceous, Paleogene-Neogene volcanic rocks in oil- and gas-bearing basins in China, which are mainly distributed in the Junggar Basin, Songliao Basin, Bohai Bay Basin, etc. There are mainly intermediate rocks and acidic rocks in east China, and intermediate rocks and basic rocks in west China. They primarily develop in intracontinental rift settings and island arc environments.

| 5 | Voltage regulation in LV grids by coordinated volt-var control strategies显示文摘The increasing penetration level of photovoltaic(PV)power generation in low voltage(LV)networks results in voltage rise issues,particularly at the end of the feeders.In order to mitigate this problem,several strategies,such as grid reinforcement,transformer tap change,demand-side management,active power curtailment,and reactive power optimization methods,show their contribution to voltage support,yet still limited.This paper proposes a coordinated volt-var control architecture between the LV distribution transformer and solar inverters to optimize the PV power penetration level in a representative LV network in Bornholm Island using a multi-objective genetic algorithm.The approach is to increase the reactive power contribution of the inverters closest to the transformer during overvoltage conditions.Two standard reactive power control concepts,cosu(P)and Q(U),are simulated and compared in terms of network power losses and voltage level along the feeder.As a practical implementation,a reconfigurable hardware is used for developing a testing platform based on real-time measurements to regulate the reactive power level.The proposed testing platform has been developed within PVNET.dk project,which targets to study the approaches for large PV power integration into the network,without the need of reinforcement. | Miguel JUAMPEREZ Guangya YANG Søren Bækhøj KJÆR | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，4： | 10 |
| 6 | A two-step lineage reprogramming strategy to generate functionally competent human hepatocytes from fibroblasts显示文摘Terminally differentiated cells can be generated by lineage reprogramming,which is,however,hindered by incomplete conversion with residual initial cell identity and partial functionality. Here, we demonstrate a new reprogramming strategy by mimicking the natural regeneration route, which permits generating expandable hepatic progenitor cells and functionally competent human hepatocytes. Fibroblasts were first induced into human hepatic progenitor-like cells (hHPLCs), which could robustly expand in vitro and efficiently engraft in vivo. Moreover, hHPLCs could be efficiently induced into mature human hepatocytes (hiHeps) in vitro, whose molecular identity highly resembles primary human hepatocytes (PHHs). Most importantly, hiHeps could be generated in large quantity and were functionally competent to replace PHHs for drug-metabolism estimation, toxicity prediction and hepatitis B virus infection modeling. Our results highlight the advantages of the progenitor stage for successful lineage reprogramming. This strategy is promising for generating other mature human cell types by lineage reprogramming. | Bingqing Xie Da Sun Yuanyuan Du Jun Jia Shicheng Sun Jun Xu Yifang Liu Chengang Xiang Sitong Chen Huangfan Xie Qiming Wang Guangya Li Xuehui LYU Hui Shen Shiyu Li Min Wu Xiaonan Zhang Yue Pu Kuanhui Xiang Weifeng Lai Peng Du Zhenghong Yuan Cheng Li Yan Shi Shichun Lu Hongkui Deng | 2019 | Cell Research2019，29，9： | 9 |
| 7 | 基于实验经济学仿真构建碳排放交易的多代理模型显示文摘碳排放交易的市场效率及减排效果受各类角色及大量参与者决策的影响,参与者特别是市场设计者及监管者必须掌握其行为及机理。实验经济学通过真实实验人参与的实验,反映参与者的有限理性。但其实验规模受限于合格实验者的数量,而多场景实验之间的可比性还受限于实验者的专注度。为此采用了一种混合交互仿真法,先通过实验提炼出真实实验人群在碳排放交易中的不确定行为的关键变量及规律,据此建立具有相同分布特性的多代理随机模型。此后就只需动用少量真实实验人来反映特殊的决策者,并与上述模型生成的大量多代理交互仿真。在保持实验经济学特点的同时,克服了其对实验规模的限制,并保证了重复实验的统计一致性。 | 蒋超 薛禹胜 黄杰 Qiuwei WU Guangya YANG | 2014 | 电力系统自动化2014，38，17： | 8 |
| 8 | Allocation of synchronous condensers for restoration of system short-circuit power显示文摘Modern power systems,employing an increasing number of converter-based renewable energy sources(RES)and decreasing the usage of conventional power plants,are leading to lower levels of short-circuit power and rotational inertia.A solution to this is the employment of synchronous condensers in the grid,in order to provide sufficient short-circuit power.This results in the increase of the short-circuit ratio(SCR)at transmission system busbars serving as points of interconnection(POI)to renewable generation.Evaluation of the required capacity and grid-location of the synchronous condensers,is inherently a mixed integer nonlinear optimization problem,which could not be done on manual basis considering each type of machine and all bus-bars.This study therefore proposes a method of optimal allocation of synchronous condensers in a hypothetic future scenario of a transmission system fed by renewable generation.Total cost of synchronous condenser installations in the system is minimized and the SCRs at the POIs of central renewable power plants are strengthened.The method has potential for application on larger grids,aiding grid-integration of RES. | Emanuel MARRAZI Guangya YANG Peter WEINREICH-JENSEN | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，1： | 7 |
| 9 | Multi-agent modeling and analysis of EV users' travel willingness based on an integrated causal/statistical/behavioral model显示文摘An electric vehicle(EV) centred ecosystem has not yet been formed, the existing limited statistic data are far from enough for the analysis of EV users' travel and charge behaviors, which however tends to be affected by many certain and uncertain factors. An experimental economics(EE)-based simulation method can be used to analyze thebehaviors of key participants in a system. However, it is restricted by the system size, experimental site and the number of qualified human participants. Therefore, this method is hard to be adopted for the behavioral analysis of a large number of human participants. In this paper, a new method combining a questionnaire statistics and the EEbased simulation is proposed. The causal relationship is considered in the design of the questionnaires and data extraction, then a multi-agent modeling integration method is introduced in the EE-based simulation, which enables the integration of causal/statistical/behavioral models into the multi-agent framework to reflect the EV users' travel willingness statistically. The generated multi-agents are used to replace human participants in the EE-based simulation in order to evaluate EV users' travel demands in different scenarios, and compare the differences of simulated or measured travel behaviors between potential EV users and internal combustion engine(ICE) vehicle users. | Juai WU Yusheng XUE Dongliang XIE Kang LI Fushuan WEN Junhua ZHAO Guangya YANG Qiuwei WU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，6： | 7 |
| 10 | Effect of repetitive square voltage frequency on partial discharge features显示文摘The inverter-fed motor is a key component of environmental-friendly hybrid cars, high-speed trains, and other industrial applications. After the widespread use of inverter-fed motors, the repetitive impulse surges from inverters were found to cause new insulation problems in inverter-fed motors that were linked to premature insulation failure. The partial discharge (PD) induced by the overvoltage inner stator windings was found to be the root cause of insulation reliability problems. To mitigate this problem, PD detection and life testing at repetitive square voltages should be performed on new types of insulation models and entire motor insulation systems. The obtained partial discharge inception voltage (PDIV) and lifetime of insulation in the tests can be used to evaluate the insulation status of inverter-fed motor insulation systems and thus to improve the insulation designs. At AC voltage conditions, the voltage frequency can significantly affect PD activity. At repetitive square voltage with rapid rise time, the influence of the square voltage frequency on PD activity should be investigated (1) to suggest values for the repetitive square voltage frequency selection for the PDIV and lifetime tests, and (2) to increase the signal-to-noise ratio when extracting PD pulses from strong disturbances generated by the operating switch of impulse generators. Therefore, the main purpose of this paper was to investigate the effects of repetitive square voltage frequency on PD events. Insulation models of both Type I (low-voltage inverter-fed motor) and Type II (high-voltage inverter-fed motor) were used to obtain single-PD and multi-PD statistical features, respectively. Experimental results indicated that higher frequencies caused less PD events with lower PD magnitudes and shorter delay times in one square voltage cycle. This phenomenon was attributed to the different surface charge decay ratios and the initial electron emission probabilities resulting from different square voltage frequencies. Finally, a number of considerations for PD measurements on inverter-fed motors were provided to improve the sensitivity of the PD test system and to obtain high objective insulation lifetime test results, which are used to assess the insulation status of inverter-fed motors. | WANG Peng WU GuangNing LUO Yang ZHU GuangYa | 2013 | Science China(Technological Sciences)2013，56，6： | 6 |

| 12 | Waterlogging stress in cotton:Damage, adaptability, alleviation strategies, and mechanisms显示文摘Over the last few decades,waterlogging stress has increasingly threatened global cotton production.Waterlogging results in reduced soil oxygen,impairing the growth and development of this valuable crop and often resulting in severe yield loss or crop failure.However,as cotton has an indeterminate growth habit,it is able to adapt to waterlogging stress by activating three mechanisms:the escape,quiescence,and self-regulating compensation mechanisms.The escape mechanism includes accelerated growth,formation of adventitious roots,and production of aerenchyma.The quiescence mechanism involves reduced biomass accumulation and energy dissipation via physiological,biochemical,and molecular events.The self-regulation compensation mechanism allows plants to exploit their indeterminate growth habit and compensatory growth ability by accelerating growth and development following relief from waterlogging stress.We review how the growth and development of cotton is impaired by waterlogging,focusing on the three strategies associated with tolerance and adaptation to the stress.We discuss agronomic measures and prospects for mitigating the adverse effects of waterlogging stress. | Yanjun Zhang Guangya Liu Hezhong Dong Cundong Li | 2021 | The Crop Journal2021，9，2： | 4 |

| 14 | Mission evaluation: expert evaluation system for large-scale combat tasks of the weapon system of systems显示文摘Mission evaluation is a new requirement for capability evaluation of the weapon system of systems(WSOS) in the era of big data, and is based on evaluating large-scale tasks with similar attributes. The use of traditional methods by military experts to evaluate large scale tasks incurs significant time cost and results in low accuracy, and is caused by a variety of factors that cause confusion. Therefore, we developed a system to assist military personnel in improving the efficiency of mission evaluation; the main innovations of our work include the qualitative and quantitative visualization of complex information is realized in a three-pane interface. We also realize the iterative and interactive evaluation modes of large-scale tasks by using the active learning method; moreover, the overall display of large-scale task evaluation results is realized using statistical graphics. In practical application, the system not only improves the users' efficiency and accuracy scores, but also helps to achieve the recognition evaluation for the overall scoring results. | Jianfei DING Guangya SI Jun MA Yanzheng WANG Zhe WANG | 2018 | Science China(Information Sciences)2018，61，1： | 4 |

| 16 | LSTM-based Energy Management for Electric Vehicle Charging in Commercial-building Prosumers显示文摘As typical prosumers,commercial buildings equipped with electric vehicle(EV)charging piles and solar photovoltaic panels require an effective energy management method.However,the conventional optimization-model-based building energy management system faces significant challenges regarding prediction and calculation in online execution.To address this issue,a long short-term memory(LSTM)recurrent neural network(RNN)based machine learning algorithm is proposed in this paper to schedule the charging and discharging of numerous EVs in commercial-building prosumers.Under the proposed system control structure,the LSTM algorithm can be separated into offline and online stages.At the offline stage,the LSTM is used to map states(inputs)to decisions(outputs)based on the network training.At the online stage,once the current state is input,the LSTM can quickly generate a solution without any additional prediction.A preliminary data processing rule and an additional output filtering procedure are designed to improve the decision performance of LSTM network.The simulation results demonstrate that the LSTM algorithm can generate near-optimal solutions in milliseconds and significantly reduce the prediction and calculation pressures compared with the conventional optimization algorithm. | Huayanran Zhou Yihong Zhou Junjie Hu Guangya Yang Dongliang Xie Yusheng Xue Lars Nordström | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，5： | 3 |
| 17 | Main controlling factors for hydrocarbon reservoir formation and petroleum distribution in Cratonic Area of Tarim Basin显示文摘The Cratonic Area of the Tarim Basin is lo-cated in the central part of the basin, developing primarilywith Cambrian marine source rocks and secondly Middle toUpper Ordovician marine and Carboniferous-Permiantransitional facies source rocks. The source rocks werematured in the changeable period and space, formingmultiple hydrocarbon generating centers during the periods.The Cratonic Area experienced multiple tectonic orogenies,forming several palaeouplifts. The matching conditionbetween effective hydrocarbon generating centers and thepalaeouplifts in various periods is the main control factor forthe formation and distribution of hydrocarbon reservoirs.The palaeouplifts have experienced multiple hydrocar-bon-filling phases, several periods of modifications and evenbreakdown. The palaeouplifts and the adjacent slopesaround the effective hydrocarbon generating center composethe most favorable places for hydrocarbon accumulation.The hydrocarbon phase is related with the evolution of thehydrocarbon generating center. In the Tarim Basin’sCratonic Area, reservoirs were mostly formed during lateHercynian. The originally formed hydrocarbon reservoirswhich are adjacent to source kitchens and in the goodpreservation condition are the most favorable prospectingtargets. Hydrocarbon is richly accumulated under theregional caprock, surrounding the faulted trends, and overand below the unconformity surfaces. Reservoirs in theCarboniferous sandstone, Ordovician karstic weatheredcrust and carbonate rock inside the buried hill compose themain intervals for hydrocarbon accumulation. Carboni-ferous and Silurian sandstone pinchout reservoirs andcarbonate lithologic reservoirs with rich fractures and poresare the main targets for further prospecting. | ZHANG Guangya WANG Hongjun LI Honghui | 2002 | Chinese Science Bulletin2002，47，S1： | 3 |
| 18 | Long-term storage of lipid-like nanoparticles for mRNA delivery显示文摘Lipid-like nanoparticles(LLNs)have been extensively explored for messenger RNA(mRNA)delivery in various biomedical applications.However,the long-term storage of these nanoparticles is still a challenge for their clinical translation.In this study,we investigated a series of conditions for the long-term storage of LLNs with encapsulation of mRNA.We evaluated the stability of LLNs with different concentrations of cryoprotectants(sucrose,trehalose or mannitol)under the conditions of freezing or lyophilization processes.Through in vitro and in vivo mRNA delivery studies,we identified the optimal storage condition,and found that the addition with 5%(w/v)sucrose or trehalose to LLNs could remain their mRNA delivery efficiency for at least three months in the liquid nitrogen storage condition. | Pengxuan Zhao Xucheng Hou Jingyue Yan Shi Du Yonger Xue Wenqing Li Guangya Xiang Yizhou Dong | 2020 | Bioactive Materials2020，5，2： | 3 |

| 20 | Construction of composite indicator system based on simulation data mining显示文摘The indicator system is the foundation and emphasis in the effectiveness evaluation of system of systems(SoS). In the past, indicator systems were founded based on qualitative methods, and every indicator was mainly determined by the expert with experience. This paper proposed a brand-new method to construct indicator systems based on the repeated simulation of the scenario space, and calculated by quantitative data. Firstly, the selection of key indicators using the Gini indicator importance measure(IIM)is calculated by random forests(RFs). Then, principal component analysis(PCA) is applied when we use the selected indicators to construct the composite indicator system of SoS. Furthermore,a set of rulesare is developed to verify the practicability of the indicator system such as correlation, robustness, accuracy and convergence. Experiment shows that the algorithm achieves good results for the construction of composite indicators of So S. | Jianfei Ding Guangya Si Baoqiang Li Jingyu Yang Yu Zhang | 2017 | Journal of Systems Engineering and Electronics2017，28，1： | 3 |
